Can anyone tell from looking at this mdstat which device is the hot
spare? Is it possible? After a couple disk failures, hot removes and
hot adds, I am not sure how to tell which disks are actually in the
raid and which disk is the spare. Once I get the original failed disk
back in the game the system doesnt automatically rebuild on it but
(from what I can tell by watching the activity lights on the
enclosure) keeps it as a hot spare.
Thanks!
